IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 37,540, dated January27, 1863.

To a/ZZ whom it may concern:

Be it known that I, HoMER WRIGHT, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Lamp-Burners 5 and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanyin g drawings, making part of this specification, inwhich- Figure l is a side sectional View of my invention, taken in theline m fr, Fig. 3; Fig. 2, a side view of the same; Fig. 3, a plan ortop view ofthe same.

Similar letters of reference indicate corresponding parts in the severalgures.

This invention relates to au improvement in that class of lamp-burnerswhich are designed to be used with a draft-chimney, and has for itsobject the lighting and trimming of the wick without the necessity ofremoving the chimney from the burner.

To this end the invention consists in having the wick-tube arranged insuch a manner that it may be raised and lowered and also canted in theburner, the wick-tube being connected with a door and arrangedrelatively with an opening in4 the burner in such a manner that the doormay be drawn out from the burner and the wick-tube lowered and canted inthe same so that the upper end of the wicktube will be brought in theopening of the burner and the upper end of the wick rendered accessiblefor lighting and trimming, the wick-tube being raised and adjusted inproper position by the closing of the door.

To enable those skilled in the art to fully understand and constructmyinvention, Iwill proceed to describe it.

A represents a burner, the external form of which may correspond tothose in general use. B is the wick-tube, which may be of the ordinaryflat form. The wick-tube is itted loosely within a socket, C, the formof which corresponds to that of the wick-tube. This socket is connectedby a hinge, a, to the bottom of the burner, the socket passing throughan opening in the bottom of the burner, which opening is sufficientlylarge to admit of the socket being canted or inclined, as shown in redoutline in Fig. l. The wick-tube B has a plate, D, attached to it by ahinge, b, the pintle c of which is sufficiently long to admit of itsends passing through curved slots, d d, which are in plates,'c e, in theburner. Figs. 1 and 3. The wick-tube B is provided with the usualserrated wheels f, and a rod or shaft, g, for the purpose of raising orlowering the wick, and within the burner there is placed a shield orcover, h, which, with the plate D, forms a partition within the burnerand covers the wheels f and shaft g. To the outer end of the plate Dthere is attached an upright plate, E, which serves as a door to anopening, l1., in the side of the burner, the door closing said openingwhen adjusted to the side of the burner. The door E is perforated in thesaine way as the side of the burner, so that air will be admitted freelyinto the burner all around it, and the small projections or handles t'z' are attached to the outer side of the door E, near its lower end. Thedoor E is held snugly to the side of the burner and over the opening IL,in consequence of a small lip, j, at the lower end of the opening h,fitting in asmall slot, 7c, at the outer end of the plateD, at thejunction of the latter with the door E. A similar slot, Z, is made inthe inner end of the plate D, adjoining the hinge b. (See Figs. 1 and3.)

When the burner is in use, the wick-tube B is in the usual verticalposition, it being thus retained by the lipj fitting in the slot kin theplate D, and when it is necessary to light or trim the wick the operatorgrasps the handles i i of the door E, and slightly raises it so that theplate D will be free from the lip j. The door E and plate D are thendrawn outward, and the wick-tube B is pressed down and canted orinclined so that its upper end will be in or project through the openingh, and the upper end of the wick rendered accessible for trimming orlighting. This position of the wick-tube is shown in red outline in Fig.l, and its adjustment in said position is due to the hinged socket C andthe curved slots d in the plates e. When the wicktube is adjusted inthis position, it is thus retained by the lipj tting in the slot Z inthe inner end of plate D. In order to adj ust the wick-tube Brin avertical position, the inner end of the plate D is gently raised so asto be free from the lip j, and the plate D is shoved inward or into theburner until the door E comes in contact with the side thereof andcovers the opening h, the lip j entering the slot 7c of plate D. By

(See

this arrangement it Will be seen that the Wiel; may be lighted andtrimmed Without removing the chimney from the burner. The canting orinelining of the Wick-tube renders the top ofthe Wick accessible to theshears. rlfhis result cannot be obtained by a simple opening in theburner.

Having thus described my invention, what l. claim as new, and desire tosecure by Letters Patent, is-

l. Arranging the wick-tube B in sueh a manner that it may be eanted oriuelined and its upper end brought in or made to project through anopening, h, in the burner, substantially as and for the purpose hereinset forth.

2. The hinged socket C in combination with the plate l), door E, andslotted plates e e, arranged as shown, and used in Connection with andapplied to the wick-tube B, to operate or adjust the latter, as and forthe purpose specified.

3. The lip j, at the lower end of the opening h in the burner, ineonneetion with the slots 7c l in the plate D, t'or the purpose ot'retaining the Wick-tube B in the two positions herein described. p
